PAPER FEEDING- ANI) SEVERING MECHANISM FOR MANIFOLDING-MACHINES.

Specification of Letters Patent.

Patented J 11110 2, 1914.

Application filed May 31, 1913. Serial No. 770,954.

To all ltiI/Jllt it may concern lie it known that I, ALBERT Kniin'rn, a citizen of the United States, residing at lilamiltcm in the county of Butler and State of Ohio, have invented certain new and useful improvements in Paper Feeding and Severiing Mechanism for hilanifolding-hflachines, of which the following is a specificat'ion.

My invention relates to manifolding apparatus and nrimarily to a type of machine wherein invariable constant lengths of paper are advanced and severed from a continuous sheet or strip. in this class of machine usually a plurality o f rolls of paper are journaled in parallelism within a casing with their ends brought over a writing table and gripped between feeding mechanism for advaluing the strips. relatively superposed as a unit. Manifolding material is inserted between the portion of the sheets over the writing table whereby an entry made upon the uppermost or exposed sheet will be transferred to the sheets beneath the same. The sheets or strips usually contain a preprinted blank or text in multiple successive numbers, with all the sheets of a series correspcmdiug relatively so that the blanks can be disposed in registry over each other. llherefore with the sheet subdivided into equal length intervals, a measured movement of advance is required to a delivery point, so that it can be severed from its succoeding interval at the divisional line or spacing se 'iarating the same and such meas ured advance is especially essential when the severing is automatically accomplished and progressively after the advance of the paper within a cycle or period of operation of the n'opelling mechanism, and the succecding length or interval. properly positioned over the writing table.

The apparatus disclosed herein is manually operated by a crank handle which is arrested or checked in its motion at the limit of a measured advance of the paper by engaging a rigid stop element and releasable therefrom for a second operation. Thus constant invariable lengths can be sued from the machine without requiring the operator to observe the advance of the paper, or delicate manipulation. Tlhis invention. however, is primarily concerned and directed to the severing mechanism and 'ts particular adaptation to manifolding machines, operated progressively after a measured advance of the paper, and within a measured cycle of the 'iropelling mechanism therefor. d

. The principal object of my invention is in the provision of an oscillating cutter member having a cutter blade mounted thereon cii'cumferentially, with its cutting edge angular longitudinally from one end toward the other so that in its arc of movement it will. be progressively engaged with a relatively stationary cutter blade or edge, approximately in a diametric line of the arc of cutter travel.

Another object of my invention is to pro vide a segmental knife supporting drum r0- tatively mounted and yieldingly urged toward a stationary cutter, the ends of the drum lmving circumferential guiding means adapted to engage with the stationary cutter or an abutment to limit the urging move ment of the drum in its normal position or a non-cutting movement of cutter blade mounted upon the drum.

Various other features of my invention relate to the combination of cutter and paper feeding mechanism in relative geared connection. with a. propeller handle for a posi' tive operation of the parts when active but of an arrangement peri'nitting independent operation of both feeding and severing mechanism progressively one after the other within a measured stroke of the propeller handle. all of which will be more fullv set forth in the description of the accompanying drawings forming a part of this specification, in which Figure l is a side ole ation of my appara tus. Fig. 2 is a central vertical section through the 'lo-rward portion thereof illustrating the feeding and severing mechanism. Fig. '3 is a side view opposite from that shown in Fig. 1. of the forward portion of the apparatus. Fig. l is a section on line 4--4lof Fig. 2. Fig. is a detail plan view of the rotative cutter shown in Figs. 1 and Fig. t is a cross section through a moditied cutter.

The claims of this invention are founded upon structural improvements over that shown in a pending application filed February 27, 1913, Serial No. 751,0l8. The general organization of the machine is in many respects similar to that shown and described in said pending application especially as it relates to the paper supporting and feeding n'uchanism and therefore reference will only be made to such features as are necessary to aid in a clear um'lerstanding of this inven tion.

1 represents the side frames of the machine supported upon a base 2. These side frames may be of sectional or integral form, between which the webs of paper are sup ported. The ends of each web of paper are brought together over a writing table in the usual manner and fed between the feeding rolls 3 and 4. The roll 3 having its axis supported in a rigid bearing, and the roll 4 has its axis supported in sliding hearings in the side frame and yieldingly urged toward the axis of roller 3 for maintaining the peripheries of the rolls 3 and st in frictional contact with each other, to grip the paper threaded between them.

At one end of the upper roll 4 a gear is provided in mesh with a gear 6 fixed to the axis of the lower roll for positively rotating the rolls in unison and prevent slippage of the rolls in a paper feeding operation. The pinion 6 of the lower roll is in mesh with a pinion 7 fixed upon a sleeve 8, see Fig. at, said sleeve being suitably journaled in a bearing formed in one of the side frames. The pinion 7 is adapted to mesh with the mutilated master gear 9 fixed to the shaft 10, said shaft extending across and journal ing in both of the side frames. As will be seen from Fig. 1, a portion of the teeth of gear 9 are cut away to produce an idle period to the feeding rolls during a portion of a complete rotation of the gear 9, the purpose being to arrest the motion of the feed rolls or discontinue the advance of the paper during a severing operation, which severing operation progressively follows the discontinuance of the feed of the paper in making a complete revolution of the gear 9.

One end of shaft 10 is provided with a two-part crank handle 11, and it may be made of extensible form, so that the handle portion 12 can be moved in a direction away from the axis of the handle or shaft 10 for releasing the handle from the stop projection 13, with which the handle engages to limit or check its rotation, and definitely locate the end of an operative cycle necessary to produce the measured advance and severance of an interval length of paper. A spring is utilized to normalize the handle portion 12 after it clears the projection 13, which is shown in dotted lines, Fig. 1. A handle of this character has been described in detail in the aforesaid pending application, but as far as the aspect of this invention is concerned any kind of propelling mechanism may be employed for producing a measured stroke or advance of the paper and operate the severing mechanism within a cycle of an invariable nature, for delivering the cut lengths of paper heretofore speci tied. The opposite end of the shaft 10 has a mutilated gear 14 fixed thereto, see Figs. 3 and st, its teeth adapted to intermesh with the pinion 15 fixed upon the pintle or axis 16 of the rotating knife drum 1?. The. nontoothed portion of the mutilated gear 14 is relatively proportioned to the toothed portion of gear 9 and the toothed portion of said gear 1% with the non-toothed portion of the gear 9 and relatively arranged so that when gear 9 is transmitting motion to gear or pinion 7, the gear 1% will rotate idly and when a reverse period exists, gear 15 will be rotated while gear 7 is idle, during a rotative interval of the main driving shaft 10. This prevents an advance of the paper toward the cutters, which might have a tendency to choke the cutters or disturb the accuracy of the feed or alinenient.

The cutter mechanism herein comprises an oscillating or rotating cutter member having a removable or renewable cutter blade, which cooperates with a relatively stationary cutter bar. The cutter mechanism in detail comprises a segmental drum 17, its ends provided with annular flanges or disks 19 from which the pintles 16 forming the axis of the drum project. These are suitably journaled in bearings formed in the side frames, and to one of which the gear 15 is fixed, as heretofore set forth. The bearings for the pintles of the drum are of an elongated form horizontally with bearing blocks 21 slidably mounted within said bearing slots, each engaged by a spring for forcing the drum to ward the stationary cutter bar 22. The cutter bar 22 is rigidly mounted between side frames each end thereof having an arcuated flange engaging respectively with a disk W 19 of the rotative knife drum to limit or confine the movement of the drum toward the stationary cutter during a normal or noncutting position of the drum and maintain the parts in a relative operative position under pressure toward each other. The periphery of the drum, as shown in Fig. 2 is provided with a knife blade 24: secured thereon by screws 25, rendering the same readily removable for grinding or renewal without dismantling the drum, driving mechanism or machine. The cutting edge of the blade 24 is angled longitudinally from one end toward the other, as illustrated in Fig. 5, whereby the cutting edge will be progressively engaged with the cutting edge of the stationary cutter bar 22, to produce a shear cut when the drum is rotated.

The blade 24 made of comparatively thin metal and is longitudinally adjustable to aline the same with the cutting edge of the stationary cutter member. The drum at several points throughout the length of the blade is provided with a series of adjusting screws 35, bearing against the blade 21-. This enables a delicate adjustment of the blade after which it is rigidly clamped in position by the screws 25. In a normal position ot the cutters their cutting edges are separated from each other to provide an opening ap proximately tangent with the :leeding rolls, so that as the paper is advanced it will he directed between the cutters in position to be severed. The drum has an oscillating action, and is moved forwardly toward the stationary cutter by the gearing heretofore de' scribed, and as soon as the last tooth of the mutilated or segment gear 14 is released from the teeth of gear 15, the drum will be quickly returned to its normal position by a spring 33 having one end fixed to the pintle, and its opposite end to the frame of the machine. The limit of reverse movement of the knife. drum may be designated by a stop or a complete release of the spring tension, this feature being optional as far the teatures of this invention are concerned.

it is i'i'ianitest that tl e knife drum may be provided with a plural. number oil peripheral segments for supporting a number of knifeblades, and its operation rotativc instead of oscillating. in which a successive kniie edgeis serially advanced toward a cutting position within the province of this invention, and the knife-blade maybe of such a l OI'IH as illustrated in the modified View, Fig. (3, in which it is secured upon an angular edge of the segment of the drum instead of on its pcriphery.

ln Fig. 4- l have illustrated mechanism for releasing or separating the feeding rolls from their peripheral contact, the mechanism comprising a rock shaft 26 journaled in the side frames, and in this instance, one end is journaled within the sleeve hub 8 of the gear 7, and the opposite end is provided with a. handle 27 for manually rocking said shaft. 28 represents a pinion fixed on the shaft 26 in mesh with a pinion 29 fixed on the JTOQl-Sl1lft 80 journaled in the sidetramcs. The rock shaft 30 has a pair of pins 31, each is adapted to respectively engage one end of a pair of hell. crank arms 32 loosely pivoted on the axis of the lower roll 3 and having their upper ends positioned to engage the axis of the upper roll 4- to raise the same when the shaft 26 is rocked.
